[A clinico-epidemiological study on the efficacy of thymopentin therapy in patients with chronic bronchitis and cellular immunity deficiency].

The immunological in vivo effects of thymopentin (TP5) treatment in eleven hypo-anergic patients affected with chronic bronchitis are reported. Significant improvement of cellular immunity, evaluated by skin tests, and an increase of percentage of CD4+ cells and natural killer activity are demonstrated. The clinical evaluation showed an evident reduction of infectious episodes of acute bronchitis after TP5 treatment.
